%  NOTICE: DO NOT MODIFY THIS FILE WITHOUT CHANGING ITS NAME. This style
%  file is called aaai.sty. Modifications to this file are permitted,
%  provided that your modified version does not include the acronym "aaai"
%  in its name, that credit to the authors and supporting agencies is
%  retained, and that further modification or reuse is not restricted. This
%  file was originally prepared by Peter F. Patel-Schneider, liberally
%  using the ideas of other style hackers, including Barbara Beeton. It was
%  modified in April 1999 by J. Scott Penberthy and George Ferguson. It was
%   modified in 2007 by AAAI. The preparation of this file was supported by 
%  Schlumberger Palo Alto Research, AT\&T Bell Laboratories, AAAI, and 
%  Morgan Kaufmann Publishers.

%  WARNING: This style is NOT guaranteed to work. It is provided in the
%  hope that it might make the preparation of papers easier, but this style
%  file is provided "as is" without warranty of any kind, either express or
%  implied, including but not limited to the implied warranties of
%  merchantability, fitness for a particular purpose, or noninfringement.
%  You use this style file at your own risk. Standard disclaimers apply.
%  
%  Do not use this file unless you are an experienced LaTeX user. To
%  satisfy AAAI's requirements, you must change your paper's configuration
%  to use Times fonts. AAAI will not accept your paper if it is formatted
%  using obsolete type 3 Computer Modern bitmapped fonts. Please ensure
%  that your version of dvips maps to type 1 fonts. Place this document in
%  a file called aaai.sty in the TeX search path. (Placing it in the same
%  directory as the paper should also work.)
%  
%  There are undoubtably bugs in this style. If you would like to submit
%  bug fixes, improvements, etc. please let us know. Send to press03@aaai.org.

% \pubnote is for printing the paper yourself, and should not be used in

% Author information can be set in various styles:
% For several authors from the same institution:
% \author{Author 1 \and ... \and Author n \\
%  Address line \\ ... \\ Address line}
% if the names do not fit well on one line use
% \author{Author 1 \\ {\bf Author 2} \\ ... \\ {\bf Author n} \\
%  Address line \\ ... \\ Address line}
% For authors from different institutions:
% \author{Author 1 \\ Address line \\ ... \\ Address line
%  \And ... \And
%  Author n \\ Address line \\ ... \\ Address line}
% To start a separate ``row'' of authors use \AND, as in
% \author{Author 1 \\ Address line \\ ... \\ Address line
%  \AND
%  Author 2 \\ Address line \\ ... \\ Address line \And
%  Author 3 \\ Address line \\ ... \\ Address line}
% If the title and author information does not fit in the area allocated,
% place \setlength\titlebox{<new height>} after the \documentstyle line
% where <new height> is something like 2.5in
% NOTE: Some laser printers have a serious problem printing TeX output.
% These printing devices, commonly known as ``write-white'' laser
% printers, tend to make characters too light. To get around this
% problem, a darker set of fonts must be created for these devices.

%%%% named style for aaai, included here for ease of use
% This section implements citations for the ``named'' bibliography style,
% modified for AAAI use.
% This file can be modified and used in other conferences as long
% as credit to the authors and supporting agencies is retained, this notice
% is not changed, and further modification or reuse is not restricted.
% The ``named'' bibliography style creates citations with labels like
%  \citeauthoryear{author-info}{year}
% these labels are processed by the following commands:
%  \cite{keylist}
%   which produces citations with both author and year,
%   enclosed in square brackets
%  \shortcite{keylist}
%   which produces citations with year only,
%   enclosed in square brackets
%  \citeauthor{key}
%   which produces the author information only
%  \citeyear{key}
%   which produces the year information only
